The bone:
Bone tissue is the highest degree of specialization among the connective tissue. It is a solid tissue. Most of the skeletal structure of the upper vertebrates consists of cells, fibers and base material, but the characteristic characteristic of bone is the presence of inorganic salts in its essential material, which is the cause of its hardness, including calcium phosphate, calcium carbonate and other salts.
The bone is surrounded by a fibrous fibroysteum of the fibrous bone, and the bone cavities inside are filled with the pure tissue Marrow tissue.
The bone is characterized by two types according to its hardness: the solid or dense bone, usually external to the spongy bone, and usually the internal site.
